JOHN N. BSELL, OE BOSTON, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE 'MACHINERY COMPANY, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

To all whom it may concern.'

Be it known that I, Jol-IN N. BUsnLL, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain lmprovements in Dust-lloods, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several gures.

This invention relates to dust hoods designed to be used on machines for abrading, scouring or triimning portions of boots or shoes, such as the heel or sole edges.

ln machines of this general character the tools necessarily are driven at a very high speed and their action upon the work produces a great quantity of dust and chips which, if not carried away in some manner, subject the workman to great annoyance and, by working into the bearings and running parts of the machine, seriously impair its running qualities. ln order to avoid this condition many forms of dust hoods have been devised and connected with some form of an exhaust apparatus to catch the dust and shavings thrownfrom the tools and conduct them away from the machine. Such hoods, however, have usually been so constructed heretofore that they have interferred with the proper manipulation of the shoe during the operation of the tool thereon.

It is the purpose of this invention to provide a dust hood which, while serving effectually to catch and conduct away from the machine the dust produced by the tools, shall also be free from the objection just noted. The particular manner in which this obj ect is effected will be clearly understood from the following description of one embodiment of the invention, reference being made to the accompanying drawing, in which- Figure 1 is a view in front elevation of a machine equipped with a hood constructed in accordance with this invention; and Fig. 2 is a plan view of the board and part of the machine shown `in Fig. 1. 'I

The drawings show a commercial form of machine for trimming the edges of the soles of shoes. This machine comprises a frame 2 supporting an upper shaft 1, upon which is mounted a cutter 6 shaped to trim the forepart of the sole. Another shaft 8, also supported in the frame 2, carries a cutter 10 Specification of Letters Patent.

shaped to trim the shank portions of the sole edge, this cutter being positioned below and at one side of the forepart cutter 6.

The dust hood shown in the drawings comprises a dust trunk 12 having a horizonj tal portion and a depending portion 111 designed to be connected with any suitable exhaust system. A main branch 16 extends forwardly from the horizontal portion of the trunk 12 to a point close to the forepart cutter 6. This branch is substantially rectangular in cross section but decreases in cross sectional area4 toward its forward end. lt will be understood by those skilled in this art that the shoe is usually presented to the lower side of the cutter so that, while the hood may project somewhat overI the top of the cutter, it must be cut away below the cutter sutliciently to aord ample space in which to handle the shoe. The cutters ro tate in a clockwise direction and thus throw the chips and dust backwardly toward the trunk 12. Accordingly, the dust receiving mout-h of the branch 16 is extended downwardly and backwardly from a point adjacent to the cut-ter 6 and is flared to enable it to catch substantially all of the dust as that is thrown from the cutter 6. The rear wall 18 of the mouth is substantially vertical and extends fo-r a considerable distance below the level of the cutter where it acts as an apron to catch the dust enabling the draft of air through the mouth to carry it into the branch 16. Another branch 20 communicates with the trunk 12 and extends forward from a point beside the branch 16, diagonally away from the branch 16 and downward to a point substantially opposite the posit-ion that the heel of the shoe nor mally will occupy when the workman is trimming the forepart close to its junction with the shank on the left hand side of the shoe. (See Fig. 2.) The branch 2O is curved outwardly or offset away from the branch 16 sufficiently to position it entirely outside the range of movement of the shoe during the trimming of the forepart. From this point the branch 20 extends inwardly or toward the branch 16 to a point close to the shank cutter 10, it's dust receiving mouth being positioned adjacent to this cut* ter where it will catch the) dust and chips thrown therefrom. Since the shank portions. of the sole edge each lie in a concave curve, it will be evident then when the workman is trimming these portions of the edge the part of the shoe that extends back of the cutter must be swung into a position higher than the level ot the cutter itself. The inclination laterally and upwardly a vay from the cutter ot' that part of the branch 2O immediately behind its mouth results in leading the branch away from the position normally occupied by the shoe while it is being trimmed in a direction such that it can not interfere with the free manipulation ot the shoe. The branches 16 and 20 are joined together at their adjacent ends and the trunk 12 is telescoped over them. rEhe trunk may therefore be removed and turned into a position the re-verse of that in which it is shown, so that the part 1t can be connected with an exhaust system located above the machine. A shelf 22 connects the branches 16 and 20 and has a hole punched therethrough to receive the stem of an oil cup Q4 by which the hood may be supported upon the machine frame 2. hood may be made of sheet metal or of any other suitable material.

Having thus described my invention, what l claim as new and desire to secure by Letters Patent of the United States is l. In a sole edge trimming machine hav- The ing a forcpart cutter and a shank cutter, the shank cutter being positioned below and at one side of the forepart cutter, a dust trunk, a branch leading therefrom having a dust receiving mouth positioned adjacent to the torepart cutter, a second branch leading trom said trunk extending diagonally away from the lirst branch and downwardly to a po-int close to the shank cutter, said branch lying outside the range et movement of the shoe during the operation ot' the cutters thereon.

2. A dust hood comprising` a trunk, a branch communicating with said trunk and extending forwardly therefrom, said b anch having a dust receiving mouth, and a second branch also connnunicating` with said trunk, having a dust receiving mouth positioned at one side of and below the mouth of thc lirst branch, the part of said second branch immediately behind its mouth being olliset laterally away from the first branch.

In testimony whereof l have signed my name to this specilication in the presence ot two subscribing witnesses.
